Imagine this engineering headache: Using a wireless transmitter, you need to send 40 megabytes of data every single second (about the same amount of data as 10 YouTube videos streaming at the same time) over a distance of 100 miles.

Echodyne Corporation, a developer of metamaterials-based radar systems, says it has completed testing on its airborne Metamaterial Electronically Scanning Array (MESA)-Detect and Avoid (DAA) radar on a small Unmanned Aerial Vehicle (sUAV). The landmark tests bring the company one step closer to launching the radar commercially.

These single band solid state RF amplifiers are an ideal solution in both military and commercial marketplaces and have been designed for applications where instantaneous bandwidth, high gain and linearity are required. They’re available in 15, 25, 50, 100, 200, and 300 watt power versions and they cover the 0.7 to 6 GHz frequency range. Each model features an excellent noise figure and also provides excellent flatness across their specified frequency range.

The QPD1009 and QPD1010 are discrete GaN on SiC HEMTs operating from the DC to 4 GHz frequency range. The QPD1009 is a 15W, 50V device with an output power level of 17W at 2 GHz, and a linear gain of 24 dB at 2 GHz. The 10W, 50V QPD1010 features an output power of 11W at 2 GHz and a linear gain of 24.7 dB at 2 GHz. These two devices are housed in low thermal resistance 3 x 3 mm packages, and are ideal for wideband or narrowband amplifiers, jammers, and for military radar, civilian radar, land mobile, military radio, and test instrumentation applications.

Tools are now available from Anritsu to help technicians determine the precise location of external PIM. Using the Anritsu PIM Hunter™ probe in conjunction with a spectrum analyzer, technicians can use traditional interference hunting techniques to locate external PIM sources in the field. This white paper describes the test process as well as provides important guidelines to consider while testing.

As 5G technologies are developed to increase wireless communication data rates by a factor of 100, the design specifications of radio frequency (RF) electronics have become much more rigorous, especially for millimeter-wave (mm-wave) applications. As an alternate solution to traditional low radiation and low gain antennas, Dielectric Resonator Antennas (DRAs) operate with less conduction losses and feature high radiation efficiency when excited properly for mm-wave frequencies and beyond. This white paper presents additional DRA characteristics, and the advantages of using them for 5G technology development.

As new power amplifier (PA) technologies are released, the latest being GaN technology, an amplifier’s behavior must be thoroughly tested and evaluated to ensure the highest performance under the stress of high power pulsing signals. Since a pulsed RF signal has a time domain nature, the best way to observe the performance of an amplifier is through time domain signal analysis. This article explains how to characterize the behaviors of pulsed RF power amplifiers in radar systems with a peak power meter.

In order to generate noise power ratio stimulus signals and to measure the resulting noise power ratio of a device under test (DUT), Rohde & Schwarz offers the Noise Power Ratio (NPR) as an add-on tool for WinIQSIM / WinIQSIM2™ software. This NPR measurement technique drastically reduces measurement time compared to classic gain wobbling, and is able to characterize the linearity of a wideband amplifier over a custom frequency range. This application note provides an overview of the software, its features, hardware and software requirements, installation, parameters, and more.

The power sensor is one of the most essential RF measurement tools, and as such, it is critical to choose the best power sensor for your application. This can be difficult, however, when many choices are available with bold claims of quicker speeds and more readings per second. Sifting through datasheets can quickly become overwhelming when deciding which sensor meets the needs of any particular measurement. This white paper provides an overview of the fundamentals of RF power sensors, and presents considerations for selecting the best fit.
